Products - GPCE2048A

General Description

GPCE2048A, a 16-bit architecture sound controller, features the newest 16-bit microprocessor, µ'nSP™ (pronounced as micro-n-SP), developed by Sunplus Technology. This high processing speed assures the µ'nSP™ is capable of handling complex digital signal processes easily and rapidly. Therefore, the GPCE2048A is applicable to the areas of digital sound process and voice recognition. The operating voltage of 2.4V through 5.5V and speed of 0.16MHz through 49.152MHz yield the GPCE2048A to be easily used in varieties of applications. The memory capacity includes 24K-word ROM plus a 2K-word working SRAM. Other features include 20 programmable multi-functional I/Os, three 16-bit timers/counters, 32768Hz Real Time Clock, Low Voltage Reset/Detection, four channels 12-bit ADC (one channel built-in MIC amplifier with auto gain controller), one 14-bit DAC with push-pull amplifier and many others.
